The present invention also aims to provide a kind of device, its makes wearing and tearing reduce, and can also make mold in the most of stroke during to same direction motion with band, and movement velocity is higher than casting rate.
Further purpose of the present invention is to provide a kind of device, and it is more insensitive to damage ratio, and can also make mold in the most of stroke during to the motion of same direction with band, and movement velocity is higher than casting rate.
The present invention also aims to provide a kind of device, its manufacturing cost is lower, and can also make mold in the most of stroke during to the motion of same direction with band, and movement velocity is higher than casting rate.
Another purpose of the present invention is to provide a kind of mold that can make with comparalive ease in the most of stroke during to same direction motion with band, and movement velocity is higher than the method for casting rate.
The present invention also aims to provide a kind of method, it is lower that this method not only implements expense, and can also make mold in the most of stroke during to same direction motion with band, and movement velocity is higher than casting rate.
Above-mentioned purpose of the present invention and other purpose that shows along with following description all will realize by the present invention.
One aspect of the present invention is to provide a kind of device, and this device is in direct casting band process, and along predetermined direction mould oscillation back and forth, above-mentioned band is shaped in mold, and along the predetermined direction demoulding from mold at a predetermined velocity.This device comprises driving mechanism, and the mechanism that is used for connecting driving mechanism and mold.Bindiny mechanism comprises non-circular gear mechanism, be used for making mold with band in most of stroke of same direction motion, movement velocity is higher than predetermined speed.Described bindiny mechanism also comprises the eccentric wheel between described gear mechanism and described mold.
According to the present invention, mold is driven by non-circular gear mechanism.Similar with hydraulic vibrator to the cam following vibrator, this gear mechanism can produce oscillating movement, makes that the speed of mold surpasses casting rate in most of stroke.Yet, to compare with hydraulic vibrator with traditional cam following vibrator, this device that has a non-circular gear mechanism is fairly simple, economical, and its structure only needs maintenance and maintenance seldom, and not only wear-resistant but also anti-pollution.
By describing the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing, it is clearer that other features and advantages of the present invention will become.In the accompanying drawing:
Fig. 1 is the schematic diagram that has according to the casting apparatus of vibrator of the present invention.
Figure 1 shows that common casting apparatus, for example, be used for the cast steel material.Material solidification with fusion when this equipment comprises operation is the mold 7 of band 8.The drawing assembly (not shown) pulls out band 8 with the predetermined speed that is known as casting rate continuously along direction 9 from mold 7.
Band 8 is bonded on the mold 7 easily, therefore, takes place for preventing this phenomenon, and mold 7 will be along direction 9 double vibrationses, thereby make mold 7 alternately move to same direction with band 8, or do reciprocal motion with it.The vibration of mold 7 makes band 8 demoulding from mold 7.When mold 7 moved round about with respect to band 8, demoulding action always was easy to take place.Yet, when mold 7 and band 8 during to same direction motion, only when the speed of mold 7 is higher than casting rate, the demoulding successfully.Speed is sinusoidal variation traditional quarter butt vibrator if mold 7 resembles, so only at mold 7 and band 8 in the sub-fraction stroke of same direction motion, the demoulding successfully.
As shown in Figure 1, by make mold 7 vibrations through the improved quarter butt vibrator 10 that can improve stripping result of the present invention.Therefore, vibrator 10 is such mould oscillation 7, and it makes mold 7 in the most of stroke during to the motion of same direction with band 8, and movement velocity surpasses casting rate.
Vibrator 10 comprises a motor or driving mechanism 1, this motor has a driving shaft to link to each other with reduction box 2, reduction box 2 is provided with a pair of circular gear 2a, and this a pair of gear 2a comprises a pinion and the gear wheel with pinion on the driving shaft that is installed in motor 1.Output shaft is arranged on the gear wheel, and this root axle is contained in traditional quarter butt vibrator, is used for supporting eccentric wheel 3.Connecting rod 4 is installed on the eccentric wheel 3, connects eccentric wheel 3 and principal arm 5.Principal arm 5 with being pivotally mounted on the supporting member 11, becomes a double-arm lever in the middle of its two ends.The one arm of lever 5 and connecting rod 4 are hinged, and one arm is connected with mold 7 in addition.Leading arm 6 usefulness are pivotally mounted on the supporting member 11, also are connected with mold 7, move along direction 9 with helping to limit mold 7.
